Could you please respond to this email and say: 1- that you cancel your formal objection. 2- that you agree to the MAWG proposal to include a WebM multimedia container format mapping table as you had referred to http://www.webmproject.org 3- Do you plan to send us the WebM multimedia container format mapping table, whith the appropriate info ? http://dev.w3.org/2008/video/mediaann/mediaont-1.0/mediaont-1.0.html#iddiv4x2x27165 Best, Thierry Le 12/10/2010 08:54, Thierry MICHEL a écrit : > Silvia, > > This is exactly what I have told James, in my earlier email in response > to his last call comment. > http://lists.w3.org/Archives/Public/public-media-annotation/2010Sep/0225.html > > extract: > "To focus on your request to include VP8 and speex in our Ontology, the > mapping tables are intended for multimedia *metadata formats*. > - VP8 is an open video compression format (codec). > - Speex is a free audio codec for Free Speech. > These are not *metadata formats*, and therefore not meant to be listed > in our mapping tables". > > As James raised an objection if this 2 formats were not included, I have > asked him to provide the 2 mapping tables for Speex and VP8, and see > what he could provide ... > > And, as we had concluded in the MAWG that on the container carries > metadata, I have in a couple of emails asked James to provide a mapping > table for the media container formats WebM. > > an pointed to the template to use > http://www.w3.org/2008/WebVideo/Annotations/drafts/ontology10/CR/mapping_table-php.html > > > I am still waiting for James to provide this information if he wants to > see it in the spec.
